I think the shot with the Veyron was a chop. It looks darn realistic if it is, though I'm not completely sure if it is a chop or not.
I seem to remember a story on WR about how the artist carefully rendered the two cars together in that shot. Awesome work.
Confirmed:
"Truth-time: this photo never actually happened. The F1 and the Veyron were shot separately, then placed together perfectly by our guys at Gecko Imaging. But we couldn’t have done it without the wonderful, original photos by Gus Gregory and Richard Meaden."
